Home Test Methods Rock Testing Constant rate of strain (CRS) Consolidation Rock Test Equipment Constant rate of strain (CRS) Consolidation Rock Test Equipment Provides a controlled ramp of strain while the back pressure is maintained. There is also the option to limit the rate of strain if a specified hydraulic gradient across the sample is exceeded. The following rock test equipment can perform the Constant rate of strain (CRS) Consolidation rock test:- Interface Shear Tester for constant rate of strain (crs) consolidation rock test GDS Small-Strain Hollow Cylinder Apparatus for constant rate of strain (crs) consolidation rock test GDS Consolidation Testing System (Rowe and Barden Type) for constant rate of strain (crs) consolidation rock test GDS Constant Rate of Strain Cell (CRS in Load Frame type) for constant rate of strain (crs) consolidation rock test
